"What is the difference between brands of GeForce??"

I don't know about the rest of them, but I know Asus makes good everything (motherboards, video cards, whatever else they make), and I hear Elsa makes pretty good video cards too. Nvidia makes the GPU, the chip that powers the video card. They do not make actual video cards for retail sale. They sell their chips to all these companies that you see selling GeForce video cards. Yes, there is a difference between brands, but I couldn't tell you which brands are good or bad except that I know Asus is good. Maybe somebody else?

The best ones to choose from are ones that stick to the Nvidia reference deseign.You can go to Nvidia site and check the specs on the card in your budget.Ignore all the tekky talk and check for only 3 things.Is the design card for(amount and type)SDRAM or ddr ram,32mb or 64mb(latter preferred)?2nd,what is the default core/mem. speed.Last of all does the card use active or passive cooling(later preferred).Passive is heatsink only and active uses a fan and heatsink.They also still produce some geforce2's and alike without any cooling method(plain chip).This is a good thing to keep away from as if the card itself even runs cool and you don't over clock,the pc tower itself can even cause lock ups and less than par performance due to its own heat issues.Write down the features,as listed here,that the card you are looking at has.Good example is geforce3.Nvidia has it listed as a card with these specs- core/mem is 200/460(ddr)64MB ram with active fan heatsink combo and T.V. out.Now you know what is par with what Nvidia designed the chip to due,so when you look for a card try to match these specs.Some companies have higher outputs than nvidia has designed for them and as I am not against this be warned that it has its problems at times and recommend avoiding this for two reasons.1-anytime the core clock speed is higher(than Nvidia spec)it is a result of over clocking which can cause instability in certain circumstances and stresses the card.2-for the same reason they often have special drivers to enable this and don't use Nvidia's reference drivers.This causes you to have less updates and increased compatibility problems.LONG story short,I have found VisionTek is a very good company that sticks right to Nvidia's outlined specs and uses Nvidia universal drivers so updates are fast and easy.I have their Geforce3 and it rocks.Hope this helps!Sorry so long.jon

Well, some have connectors for additional displays. Some have spiffy color schemes for the pcb. Still others have fans that spin when the card is on. Some have extra cards that plug onto the side. Many vendors bundle software with their geforce. Some do not. Some cards have memory that is .5ns faster than other cards. Some are clocked a bit faster, over spec.
